Unanswered: Sencha touch 2 charts: draw line on specific range

Is it possible to display certain series for line charts on the given range? E.g. I have two lines, orange occupies all plot (and x-axis are bases on its values), but I'd like a green one to end on "12" value.I tried removing data from the green line, but it didn't help.

Maybe there's a way to modify style (opacity) for the specific segments of the line?
